In this video you will see a 2002 BMW M3 E46 with the normal S54B32 engine but with a Single Turbo Borg Warner 9180 turbo making 400WHP (550 on high boost!).

The car also has KW Competition suspension, Dunlop Direzza tyres, rollcage and weighs around 1400kg with half a tank of fuel. Let me know what you thought of this car in the comments below.
